Siemens has released V5.0 to address this flaw, documented in security advisory SSA-032379. HIGH 8.8 0.0% 54
No patch
CVE-2026-69109 Unauthenticated arbitrary file read in Siemens License Server (SLS) versions prior to V5.3 allows remote attackers to traverse the filesystem and access sensitive files without any credentials. The root cause is missing sanitization of user-supplied path input (CWE-35), and the CVSS 4.0 score of 8.7 reflects network-exploitable access with no authentication or user interaction required and high confidentiality impact. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but the attack complexity is low and the attack surface is any network-reachable SLS instance. HIGH 8.7 0.5% 54
No patch
CVE-2026-46746 Authenticated command injection in Siemens SINEC INS versions prior to V1.0 SP2 Update 6 allows remote attackers to execute arbitrary OS commands as the sinecins service account by submitting crafted directory names to the /api/sftp/uploadFiles endpoint. The injected payloads are stored and triggered later when directory listings are retrieved, producing a stored/second-order command injection. No public exploit identified at time of analysis, but the CVSS 4.0 base score of 8.7 reflects high impact across confidentiality, integrity, and availability of the underlying host. HIGH 8.7 0.2% 54
No patch
CVE-2026-46748 Local privilege escalation in Siemens SINEC INS (versions prior to V1.0 SP2 Update 6) stems from a binary shipped with the Linux cap_dac_override capability, which bypasses filesystem discretionary access control checks. An authenticated local attacker can leverage this overly broad capability to read or modify any file on the system, ultimately obtaining root. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV. HIGH 8.7 0.0% 54
No patch
CVE-2025-40833 Denial of service in Siemens industrial networking equipment allows remote unauthenticated attackers to crash affected devices via specially crafted IPv4 packets, requiring manual restart for recovery.
